PROBLEM
Show/hide table
| The existing 292-7075 TOS Rotor does not preload the tapered rolling bearings correctly on certain TH31DB and TH35DB Petroleum Transmissions. This can result in the premature failure of the 2747437/">274-7437 Lip Seal. The 292-7075 TOS Rotor can be replaced with a 2755738/">275-5738 TOS Rotor to correctly preload the bearings. |
